Created attachment 154602 [details]
various JPEG XL files

Hello,

I am experimenting with CMYK in JPEG XL. I created the attached .jxl files (in testfiles.zip).
Krita always crash when I attempt to open them.

I tried with https://charlotte.kde.org/binary-factory/Krita_Nightly_Windows_Build/lastSuccessfulBuild/krita-nightly-x64-5.2.0-prealpha-6194c29fd8-setup.exe

Assigning amy, as they're responsible for the jxl support.

I can't reproduce the crash on 5.1.4 or 5.2.0 master [9d2afb5b], but instead the image just failed to load.

Also, I believe we are still currently removed the CMYK support for JXL for now?

Do you use build with libjxl 0.7 ? When it is not found, JXL support is not working.

I get segmentation fault on Linux with krita-5.2.0-prealpha-9d2afb5b7e-x86_64.appimage

I tested it with win10 system.
Anyway I confirmed the crash happens when opening the file from File->Open or right clicking the file on explorer and "Open with -> Krita".

Crash didn't happen when drag-dropping the image to Krita's window, but just didn't load as I specified before.
